N-aryl-uracile-based herbicides

ABSTRACT

The present invention provides herbicidal active compound combinations which comprise, N-aryl-uracils and herbicidally active compounds and/or compounds which improve crop plant compatibility. The combinations find use in controlling monocotyledonous and dicotyledonous weeds in crops of useful plants.

FIELD OF THE INVENTION

The invention relates to novel herbicidal active compound combinations comprising, on the one hand, known N-aryl-uracils and, on the other hand, known herbicidally active compounds and/or compounds which improve crop plant compatibility, which combinations can be used with particularly good results for controlling monocotyledonous and dicotyledonous weeds in various crops of useful plants, but also for controlling monocotyledonous and dicotyledonous weeds in the semi- and non-selective field.

BACKGROUND OF THE INVENTION

N-aryl-uracils are, as herbicidally active compounds, subject of a number of patent applications (cf. EP-A-408382, EP-A-473551, EP-A-563384, EP-A-648749, U.S. Pat. No. 4,943,309, U.S. Pat. No. 5,084,084, U.S. Pat. No. 5,127,935, U.S. Pat. No. 5,759,957, WO-A-91/00278, WO-A-95/29168, WO-A-95/30661, WO-A-96/35679, WO-A-97/01541, WO-A-98/25909). However, the known N-aryl-uracils have a number of gaps in their activity.

A number of herbicidally active compound combinations based on N-aryl-uracils have also been disclosed (cf. DE-A-4437197, DE-A-19915013, DE-A-19919951, EP-A-714602, WO-A-96/07323, WO-A-96/08151, JP-A-11189506). However, likewise, the properties of these active compound combinations are not entirely satisfactory.

DETAILED DESCRIPTION OF THE INVENTION

Surprisingly, it has now been found that a number of known active compounds from the group of the N-aryl-uracils, when used together with known herbicidally active compounds, show synergistic effects with respect to the activity against weeds and can be used particularly advantageously as broadly active combination preparations for the selective control of monocotyledonous and dicotyledonous weeds in crops of useful plants, such as, for example, cotton, cereals, grass/pasture land, maize, lawn (“turf”), rice, soyabeans, sunflowers and sugar cane, but also for controlling monocotyledonous and dicotyledonous weeds in the semi- and non-selective field.

The present invention provides herbicidal compositions, characterized in that they comprise an effective amount of an active compound combination comprising

(a) at least one N-aryl-uracil of the formula (I)

Surprisingly, it has now been found that the above-defined active compound combinations of the N-Aryl-uracils of the formula (I) and the abovementioned active compounds of Group 2 exhibit a particularly high herbicidal activity combined with very good crop plant compatibility and can be used for the selective control of monocotyledonous and dicotyledonous weeds in a variety of crops, in particular in cereals, such as, for example, wheat, barley or oats, and maize, and additionally also for controlling monocotyledonous and dicotyledonous weeds in the semi- and non-selective field. This effect is particularly pronounced in cereals. Likewise, the effect is particularly pronounced in maize.

Surprisingly, the herbicidal activity of the active compound combinations according to the invention of compounds of the abovementioned Groups 1 and 2 exceeds the total of the action of the individual active compounds considerably.

Thus, not just a complementation of actions but a synergistic effect is present which could not have been predicted. The new active compound combinations are well tolerated in a variety of crops, also effecting good control of weeds which are usually difficult to control. Thus, the novel active compound combinations are a valuable addition to the herbicides.

The synergistic effect of the active compound combinations according to the invention is particularly strongly pronounced in certain concentration ratios. However, the weight ratios of the active compounds in the active compound combinations may be varied within relatively wide ranges. In general, from 0.01 to 1000 parts by weight, preferably from 0.02 to 500 parts by weight and particularly preferably from 0.05 to 100 parts by weight of active compound of Group 2 are used per part by weight of active compound of the formula (I).

The following may be particularly emphasized as mixing components from amongst the active compounds of Group 3:

1-methyl-hexyl 5-chloro-quinoxalin-8-oxy-acetate (cloquintocet-mexyl), ethyl 4,5-dihydro-5,5-diphenyl-3-isoxazolecarboxylate (isoxadifen-ethyl) and diethyl 1-(2,4-dichloro-phenyl)-4,5-dihydro-5-methyl-1H-pyrazole-3,5-dicarboxylate (mefenpyrdiethyl), which are particularly suitable for improving the compatibility in cereals, and 4-dichloroacetyl-1-oxa-4-aza-spiro[4.5]-decane (AD-67), 1-dichloroacetyl-hexahydro-3,3,8a-trimethylpyrrolo[1,2-a]-pyrimidin-6(2H)-one (BAS-145138), 4-dichloroacetyl-3,4-dihydro-3-methyl-2H-1,4-benzoxazine (benoxacor), 2,2-dichloro-N,N-di-2-propenyl-acetamide (dichlormid), 3-dichloroacetyl-5-(2-furanyl)-2,2-dimethyloxazolidine (furilazole, MON-13900) and 3-dichloroacetyl-2,2,5-trimethyl-oxazolidine (R-29148), which are particularly suitable for improving the compatibility in maize.

It must be considered as surprising that, from amongst a multiplicity of known safeners or antidotes capable of antagonizing the harmful effects of a herbicide on the crop plants, it is precisely the abovementioned compounds of Group 3 which are capable of almost completely compensating the harmful effect, on the crop plants, of active compounds of the formula (I) and their salts, if appropriate also in combination with one or more of the abovementioned active compounds of Group 2, without adversely affecting the herbicidal efficacy towards the weeds.

Surprisingly, it has also been found that the herbicidally active substance 2,4-dichlorophenoxy-acetic acid (2,4-D) and its derivatives, too, can play the safener role described above.

Accordingly, a preferred embodiment is also a mixture comprising a compound of the formula (I) and/or salts thereof on the one hand, and 2,4-D and/or its derivatives on the other hand, if appropriate in combination with one or more of the active compounds of Group 2 listed above. Typical derivatives of 2,4-D are, for example, its esters.

Surprisingly, it has also been found that the herbicidally active substances (4-chloro-2-methylphenoxy)acetic acid (MCPA) and (+-)-2-(4-chloro-2-methylphenoxy)propanoic acid (mecoprop) can also play a safener role. The compounds mentioned are described in the following patent applications: JP 63 072 605 und GB 00 820 180.

The compounds diethyl 1-(2,4-dichlorophenyl)-4,5-dihydro-5-methyl-1H-pyrazole-3,5-dicarboxylate (mefenpyr-diethyl), 1-methyl-hexyl [(5-chloro-8-quinolinyl)oxy]acetate (cloquintocet-mexyl) and ethyl 1-(2,4-dichlorophenyl)-5-(trichloromethyl)-1H-1,2,4-triazole-3-carboxylate (fenchlorazole-ethyl) are described in the following patent applications: DE-A-39 39 503, EP-A-191 736 and DE-A-35 25 205. 2,4-D is a known herbicide.

The advantageous effect of the crop plant compatibility of the active compound combinations according to the invention is likewise particularly strongly pronounced at certain concentration ratios. However, the weight ratios of the active compounds in the active compound combinations can be varied within relatively wide ranges. In general, from 0.001 to 1000 parts by weight, preferably from 0.01 to 100 parts by weight and particularly preferably from 0.1 to 10 parts by weight of one of the crop plant compatibility-improving compounds mentioned above under (c) (antidotes/safeners) are used per part by weight of active compound of the formula (I).

All plants and plant parts can be treated in accordance with the invention. Plants are to be understood as meaning in the present context all plants and plant populations such as desired and undesired wild plants or crop plants (inclusive of naturally occurring crop plants). Crop plants can be plants which can be obtained by conventional plant breeding and optimization methods or by biotechnological and recombinant methods or by combinations of these methods, inclusive of the transgenic plants and inclusive of the plant varieties protectable or not protectable by plant breeders' rights. Plant parts are to be understood as meaning all aerial and subterranean plant parts and organs of the plants such as shoot, leaf, flower and root, examples which may be mentioned being leaves, needles, stalks, is, flowers, fruiting bodies, fruits, seeds, roots, tubers and rhizomes. The plant parts also include vegetative and generative propagation material, for example cuttings, tubers, rhizomes, seedlings and seeds.

The treatment according to the invention of the plant and plant parts with the active compounds is carried out directly or by allowing the compounds to act on the surroundings, environment or storage space by the customary treatmnent methods, for example by immersion, spraying, evaporation, fogging, scattering, painting on and, in the case of propagation material, in particular in the case of seeds, also by applying one or more coats.

Amongst the plants obtained by biotechnological and recombinant methods, or by combining these methods, plants which are emphasized are those which tolerate so-called ALS, 4-HPPD, EPSP and/or PPO inhibitors, such as, for example, Acuron plants.

The active compounds according to the invention can be used, for example, in the following plants:

Dicotyledonous weeds of the genera: Abutilon, Amaranthus, Ambrosia, Anoda, Anthemis, Aphanes, Atriplex, Bellis, Bidens, Capsella, Carduus, Cassia, Centaurea, Chenopodium, Cirsium, Convolvulus, Datura, Desmodium, Emex, Erysimum, Euphorbia, Galeopsis, Galinsoga, Galium, Hibiscus, Ipomoea, Kochia, Lamium, Lepidium, Lindernia, Matricaria, Mentha, Mercurialis, Mullugo, Myosotis, Papaver, Pharbitis, Plantago, Polygonum, Portulaca, Ranunculus, Raphanus, Rorippa, Rotala, Rumex, Salsola, Senecio, Sesbania, Sida, Sinapis, Solanum, Sonchus, Sphenoclea, Stellaria, Taraxacum, Thlaspi, Trifolium, Urtica, Veronica, Viola, Xanthium.

Monocotyledonous crops of the genera: Allium, Ananas, Asparagus, Avena, Hordeum, Oryza, Panicum, Saccharum, Secale, Sorghum, Triticale, Triticum, Zea.

However, the use of the active compound combinations according to the invention is in no way restricted to these genera, but also extends in the same manner to other plants.

The active compound combinations to be used in accordance with the invention can be employed not only in conventional cultivation methods (suitably spaced row crops), in plantation crops (for example grapevines, fruit, citrus) and in industrial plants and railtracks, on paths and squares, but also for stubble treatment and in the minimum tillage method. They are furthermore suitable as dessicants (haulm killing in, for example, potatoes) or as defoliants (for example in cotton). They are furthermore suitable for use on non-crop areas. Other fields of application are nurseries, forests, grassland and the production of ornamentals.

The active compound combinations can be converted into the customary formulations such as solutions, emulsions, wettable powders, suspensions, powders, dusts, pastes, soluble powders, granules, suspo-emulsion concentrates, natural and synthetic materials impregnated with active compound, and microencapsulations in polymeric materials.

These formulations are produced in a known manner, for example by mixing the active compounds with extenders, that is, liquid solvents and/or solid carriers, optionally with the use of surfactants, that is, emulsifiers and/or dispersants and/or foam formers.

In the case of the use of water as an extender, organic solvents can, for example, also be used as cosolvents. The following are essentially suitable as liquid solvents: aromatics such as xylene, toluene, or alkylnaphthalenes, chlorinated aromatics and chlorinated aliphatic hydrocarbons such as chlorobenzenes, chloroethylenes or methylene chloride, aliphatic hydrocarbons such as cyclohexane or paraffins, for example mineral oil fractions, mineral and vegetable oils, alcohols such as butanol or glycol and their ethers and esters, ketones such as acetone, methyl ethyl ketone, methyl isobutyl ketone or cyclohexanone, strongly polar solvents such as dimethylformamide and dimethyl sulphoxide, or else water.

Solid carriers which are suitable are:

for example ammonium salts and ground natural minerals such as kaolins, clays, talc, chalk, quartz, attapulgite, montmorillonite or diatomaceous earth, and ground synthetic materials such as highly-dispersed silica, alumina and silicates; suitable solid carriers for granules are: for example crushed and fractionated natural rocks such as calcite, marble, pumice, sepiolite and dolomite, or else synthetic granules of inorganic and organic meals, and granules of organic material such as sawdust, coconut shells, maize cobs and tobacco stalks; suitable emulsifiers and/or foam formers are: for example nonionic and anionic emulsifiers such as polyoxyethylene fatty acid esters, polyoxyethylene fatty alcohol ethers, for example alkylaryl polyglycol ethers, alkylsulphonates, alkyl sulphates, arylsulphonates, or else protein hydrolysates; suitable dispersants are: for example lignin sulphite waste liquors and methylcellulose.

Tackifiers such as carboxymethylcellulose and natural and synthetic polymers in the form of powders, granules or latices, such as gum arabic, polyvinyl alcohol and polyvinyl acetate, or else natural phospholipids such as cephalins and lecithins and synthetic phospholipids can be used in the formulations. Other additives can be mineral and vegetable oils.

It is possible to use colorants such as inorganic pigments, for example iron oxide, titanium oxide and Prussian Blue, and organic dyestuffs, such as alizarin dyestuffs, azo dyestuffs and metal phthalocyanine dyestuffs, and trace nutrients such as salts of iron, manganese, boron, copper, cobalt, molybdenum and zinc.

The formulations generally comprise between 0.1 and 95 per cent by weight of active compounds, preferably between 0.5 and 90%.

The active compound combinations according to the invention are generally applied in the form of ready mixes. However, the active compounds contained in the active compound combinations may also be applied in the form of individual formulations which are mixed upon use, that is, in the form of tank mixes.

The new active compound combinations, as such or in their formulations, may furthermore also be used as a mixture with other known herbicides, again with ready mixes or tank mixes being possible. A mixture with other known active compounds such as fungicides, insecticides, acaricides, nematicides, bird repellants, growth substances, plant nutrients and soil conditioners is also possible. It may furthermore be advantageous for specific applications, in particular for the post-emergence method, to incorporate into the formulations plant-tolerated mineral or vegetable oils (for example the commercial product “Rako Binol”) or ammonium salts such as, for example, ammonium sulphate or ammonium thiocyanate, as further additives.

The new active compound combinations can be used as such, in the form of their formulations or the use forms which can be prepared from these formulations by further dilution, such as ready-to-use solutions, suspensions, emulsions, powders, pastes and granules. Application is effected in the customary manner, for example by pouring, spraying, atomizing, dusting or broadcasting.

The active compound combinations according to the invention can be applied before and after emergence of the plants, that is to say by the pre- and post-emergence method. They may also be incorporated into the soil prior to sowing.

The good herbicidal action of the new active compound combinations can be seen from the examples which follow. While the individual active compounds show weaknesses with regard to their herbicidal action, the combinations all show a very good herbicidal action which exceeds a simple sum of actions.

A synergistic effect in herbicides is always present when the herbicidal action of the active compound combination exceeds the action of the active compounds when applied individually.

The expected action for a given combination of two herbicides can be calculated as follows (cf. COLBY, S. R.: “Calculating synergistic and antagonistic responses of herbicide combinations”, Weeds 15, Pages 20-22, 1967):

If X = % damage by herbicide A (active compound of the formula I) at an application rate of p kg/ha and Y = % damage by herbicide B (active compound of the formula II) at an application rate of q kg/ha and E = the expected damage of herbicides A + B at an application rate of p + q kg/ha, then E = X + Y − (X * Y/100).

If the actual damage exceeds the calculated value, the combination has a superadditive effect, that is to say a synergistic effect.

The theoretically expected activity for a given combination of three herbicides can likewise be found in the literature mentioned above.

USE EXAMPLES Example A

Pre-emergence-test

Solvent: 2 to 3 parts by weight of acetone or N,N-dimethyl-formamide

Emulsifier: 1 part by weight of alkylaryl polyglycol ether

To produce a suitable preparation of active compound, 1 part by weight of active compound is mixed with the stated amount of solvent, the stated amount of emulsifier is added and the concentrate is diluted with water to the desired concentration. Formulated products are dissolved in water and then diluted with water to the desired concentration.

The solutions of the other mixing components (active compounds or safeners) are prepared analogously. The separately prepared solutions of the various mixing components are then combined and, if appropriate, additional substances (formulation auxiliaries, additives, etc.) are added and, if appropriate, water is added to prepare the desired dilution.

Seeds of the test plants are sown in standard soil. After 24 hours, the soil is sprayed with the preparation of active compound such that the particular amount of active compound desired in each case is applied per unit area. The concentration of active compound in the spray liquor is chosen such that the particular amount of active compound desired in each case is applied in 500 litres of water per hectare. The containers with the test plants are kept in a greenhouse at controlled temperature and controlled illumination until evaluation.

After three weeks, the degree of damage to the plants is rated in % damage in comparison to the development of the untreated control. The figures denote

0%=no effect/no damage (like untreated control)

100%=total destruction
